Detailed Description
Embodiments of the present application will be described in detail below by way of example with reference to the accompanying drawings. The constituent elements described in the following embodiments are merely examples, and are not intended to limit the technical scope of the present application.
[ embodiment 1 ]

As shown in fig. 1, the information processing apparatus 100 is an apparatus for generating a machining program for performing machining including a plurality of machining steps, and includes a display unit 101 and a machining program generation unit 102.

[ embodiment 2 ]
Next, a machine tool system 200 according to embodiment 2 of the present application will be described with reference to the drawings from fig. 2. Fig. 2 is a diagram for explaining the overall configuration of the machine tool system 200 according to the present embodiment.
(System integral constitution)
The machine tool system 200 includes an information processing device 201 and a CNC (numerical control machine) 202.
Examples of the machine tool 202 include a machine that applies additive processing (Additive Manufacturing) to a workpiece, a machine that applies additive processing (Subtractive Manufacturing) to a workpiece, a machine that performs processing by irradiating light such as laser light, and the like. Specifically, the present application is applicable to machines such as a machine tool, a drilling machine, a boring machine, a milling machine, a gear cutting machine, a grinding machine, a multi-axis machining machine, a laser machining machine, and a laminating machine, which are numerical controlled by NC (Numerical Control: digital control) programs to perform various machining operations such as turning, cutting, punching, grinding, polishing, rolling, forging, bending, molding, micromachining, and laminating on a workpiece such as a metal, a wood, a stone, or a resin. The machine tool 202 may have a measurement function, or may be configured to be able to measure the size of a workpiece using a measuring instrument such as a touch probe or a camera.
The machine tool 202 is, for example, a three-axis machine tool, and includes a spindle motor 226 and a feed shaft motor 227 as mechanical elements. The spindle motor 226 rotates the tool, and the feed shaft motor 227 may linearly move the table in the X, Y axis direction or linearly move the tool or the table in the Z axis direction by a ball screw or the like. The machine tool 202 may of course be a 5-axis machine.
The numerical controller 220 is a device for performing numerical control of machining in the machine tool 202, and includes an NC interpreter 221 as an interpretation unit for interpreting the NC program 250, and a command output unit 222 for outputting control commands to various controllers.
The spindle motor servo controller 223 controls the spindle motor 226 based on a control instruction from the instruction output section 222. The feed shaft motor servo controller 224 controls the feed shaft motor 227 based on a control instruction from the instruction output section 222.
The numerical controller 220 interprets the NC program 250 generated by the information processor 201, recognizes a tag (note, G code called by a subroutine) in the implantation program, and outputs a special control instruction to the machine tool 202.
The information processing apparatus 201 is a so-called CAM post-processor, and generates an NC program 250 as a machining program used in the numerical controller 220 after performing process editing on CL data (cutter location data: tool position data) 230, which is tool path data acquired from the CAM 240.
The CAM240 has a main processor 241. The main processor 241 generates CL data 230 based on shape data acquired from CAD (Computer-Aided Design) 260. Here, the case where the CL data 230 is acquired from the CAM240 is described, but APT-CL data can be similarly generated by extracting necessary information by reverse engineering the NC program acquired from the CAM 240.
(constitution of information processing apparatus)
The information processing apparatus 201 includes a process editing screen display unit 211, an operation class setting unit 212, an APT (Automatically Programmed Tool: automatic programming tool) -CL data generating unit 213, an NC program generating unit 215, and a parameter table 216.
The process editing screen display unit 211 displays a process editing screen 300 shown in fig. 3 as a GUI for setting parameters of each process (=operation) as a process editing screen. The process editing screen 300 includes an operation tree display unit 301 and a parameter setting unit 302. The operation tree display section 301 displays operations in a tree structure for each system (spindle or tool head). The operation is a set of processing steps. Individual machining processes (flat machining, hole machining, slot machining, etc.) and/or successive machining processes are grouped into one operation. The process edit screen 300 of fig. 3 is an example of a machine tool having a lower tool rest, and therefore shows both the 1 st system and the 2 nd system, but only the 1 st system is shown in the case of a 5-axis machine or the like without a lower tool rest.
As shown in fig. 4, when one operation 401 is selected in the operation tree display unit 301, the parameter setting unit 302 can display the parameters of the selected operation and edit the parameters. Specifically, parameters such as a workpiece coordinate system, a coordinate system origin, an indexing angle of a rotation axis, a safety point zmax, a safety point zpitch, a dynamic fixture offset, workpiece setting error correction, and an inclined surface machining command can be edited.
As shown in fig. 5, one of the parameters displayed in the parameter setting section 302 is "operation category", and a pull-down menu is prepared for it. The user can select one from among "Rough", "Middle Finish" and "Finish" using a pull-down menu.
The operation classification setting unit 212 sets, for each operation, any one of "Rough", "Middle Finish" and "Finish" to be registered, in response to the selection of the user.
The APT-CL data generation unit 213 generates APT-CL data 214, and adds an APT command for classifying rough machining or finish machining corresponding to the registered operation classification to the APT-CL data 214. Specifically, in the case of ROUGH machining, as shown in fig. 6, an APT command 601 of "OPTYPE/ROUGH" is inserted at a predetermined position. In the case of semi-finishing, the APT command "OPTYPE/MIDDLE" is inserted at the same position, and in the case of finishing, the APT command "OPTYPE/FINISH" is inserted at the same position.
Next, the NC program generating unit 215 refers to the parameter table 216, and generates an NC program from the APT-CL data.
At this time, the NC program generating unit 215 determines which of "opt/ROUGH", "opt/MIDDLE", "opt/FINISH" the APT command described in the APT-CL data 214 is. In the NC program, instructions (G code, M code) corresponding to the APT command are described in the following modes (1) to (3).
(1) In the machining mode selection (G332), a machining mode corresponding to the purpose, that is, "time priority mode" is set for rough machining, "intermediate mode" is set for semi-finish machining, and "precision priority mode" is set for finish machining. The "time-first mode" is a mode in which the processing time is shortened to be the most preferable. The "precision priority mode" is a mode for prioritizing machining precision, and is used for machining a surface requiring machining precision and finish machining. The "intermediate mode" is an intermediate mode of the time-first mode and the precision-first mode for semi-finishing requiring precision and time.
Specifically, in the NC program, any one of "G332R 1", "G332R 2", "G332R 3", and "G332R 4" is inserted at a predetermined position (for example, after the position detection M code (M380) or the like).
The parameters R1 to R4 are set in the following cases.
R1: setting during rough machining
R2: semi-finishing time setting
R3: setting during finishing
R4: the setting is manually made by the user only in the case where the setting is desired (mode used when the user is particularly careful and wishes to process)
(2) As shown in fig. 7, in the command for performing the feed rate control based on the cutting force estimation, the feed rate is changed to make the cutting force uniform in the case of rough machining, thereby shortening the machining time. On the other hand, in the case of finishing, the cut is changed when the feed speed is frequently changed, and the quality of the surface is lowered, so that the feed speed is set to be constant. An F value corresponding to the simulation result of the cutting force is added to the NC program at the time of the post-output as the feed speed. And F values with uniform cutting force are output during rough machining.
In the cutting force simulation, a cutting force target value is calculated in consideration of tool wear, tool chatter, and the like. The feed speed is changed to approach the target value of the cutting force.
(3) Switch settings for finishing mode selection (M380, M381) are performed. These settings are the M-codes of the control tool box during finishing. If the finish machining is performed while the tool box is rotating, the machining accuracy of the machined surface may be deteriorated due to the vibration. Thus, in the case of finishing, M380 (finishing mode on) and M381 (finishing mode off) are inserted before and after the finishing program. In this way, the machine tool is controlled to finish machining after the turning of the tool box is completed.
Here, the rotation of the tool box and the timing control of the finish machining are performed, but the present application is not limited to this. A command for not allowing machining when vibration is generated from a vibration generating portion other than the tool box may be inserted into the NC program. For example, as the vibration generating portion, a chip conveyor, a pump of a refrigerant releasing portion, and the like can be cited in addition to the cutter box.
Fig. 8 is a flowchart for explaining a flow of processing by the NC program generating unit 215.
When the APT-CL data 214 is input, the NC program generating unit 215 determines the OPTYPE in step S801, and proceeds to step S803 when the rough machining is performed, and sets G332 to the time-first mode. Next, in step S805, the feed speed is set to be flexibly changed in order to shorten the processing time.
If it is determined in step S801 that the result of the OPTYPE is semi-finish machining, the routine proceeds to step S809, where the intermediate mode is set to G332, and then the process is set in step S811 to flexibly change the feed speed so as to shorten the machining time. In step S813, M380 and M381 are inserted before and after the semi-finishing command, and the tool box rotation during machining is stopped.
In step S801, when it is determined that the result of the OPTYPE is finish machining, the routine proceeds to step S815, where G332 is set to the precision priority mode, and then in step S817, the feeding speed is set to be constant. In step S819, M380 and M381 are inserted before and after the finishing command, and the tool box rotation during machining is stopped.
These control processes can be realized by referring to the parameter table 216 shown in fig. 9.
Fig. 10 and 11 show specific examples of the NC program generated by the NC program generating unit 215. When the OPTYPE/ROUGH 601 is set as the APT command in the APT-CL data 214 as shown in fig. 6, the G code and parameter 1001 of G332R 1 are inserted without inserting the code of M380 as shown in fig. 10.
In addition, a parameter of G01 is set in the cutting portion 1002 so that the feeding speed of a portion where the cutting force is high is slow, and the feeding speed of a portion where the cutting force is low is fast.
On the other hand, when OPTYPE/FINISH is set as an APT command in APT-CL data 214, as shown in fig. 11, codes 1101 of M380 and M381 are inserted, and G codes and parameters 1102 of G332R 3 are inserted. A parameter of G01 is set in the cutting portion 1103 so that the feed speed is constant.
As described above, according to the present embodiment, the user can generate a machining program set appropriately only by selecting an operation category on the selection screen, and can realize machining corresponding to rough machining or finish machining.
